DOOR-LOCK.

To all whom it may concern:

Be it known that I, HERBERT DUNDER- DALE, a citizen of the UnitedStates, residing at Cleveland, in the county of Cuyahoga and State ofOhio, have invented certain new and useful Improvements in Door- Locks,of which the following is a full, clear, and exact description,reference being had to the drawings herein. I

My invention pertains to door locking devices, and has reference moreparticularly to a lock device designed for usein connection with therear edge of a sliding door.

The invention has for one of its principal objects the provision of viceof this character co-acting to draw the rear edge of the door sidewiseagainst the doorway frame as the door is moved to closed position andthereby provide a tight closure at the rear of the door, and in whichposition the door is locked by the device against lateral or verticalmovement.

Another object is to produce a simple and eflicient lock device ofthischaracter wherein binding of the parts is eliminated, and

which is cheaply constructed, easily applied,

and-facile and positive in its operation.

A further object is the provision of a lock device constructed toprovide for, and to correct, in the closing movement of the door anysagging of the door which may be present.

These, together with such other objects as may hereinafter appear, orare incident to my invention, I attain by means of a constructionillustrated in-preferred form, I

wherein Figure 1 represents a'horizontal sectional view illustrating theapplication of my improved door lock device to a :door;

Fig. 2 is a front elevation of the same;

Fig. 3 is an end view of the device along the line III-III of Fig. 2;.

Fig. 4 is a view in perspective of the two co-acting lock members whichtogether comprisethe lock'device; and i Fig. 5, represents a slightlymodified form of my invention. i y

Referring to the drawings, the numeral 7 indicatesthe doorpost locatedat the side of the doorway, 8 the siding and 9 a fragmentary portion ofa sliding door; the doorpost having a portion 7% thereof projectingoutwardly beyond the siding '8 to provide a clearance between it and thedoor for the Specification of Letters Patent.

reception of my lock device, which latter operates to draw the rear edge10 of the door tightly up against the projecting portion of the doorpost and locks the door against vertical and lateral movement when thedoor is closed.

The lock device, as shown, consists of a locking slide member A, and areceptive socket member B of elongated shape preferably secured to thesiding closely adjacent to the projecting) portion 7 of the doorpost;the slide mem er being correspondingly inner face of the rear edge 10 ofthe door, and which comprises a base or attaching portion 11, havingintegrally formed therewith a neck 12 and a head 13 which extend intothe) clearance between the door and siding.

The socket member B of the device is dis-.

posed in the clearance and comprises the central Web portion 19,attaching base flanges 15 formed with bolt holes 15 for the reception ofthe attaching bolts 16 which pass into the siding, and connecting sidewalls 14. The web portion 19 is longitudinally inclined inwardly fromits wide open outer end to its inner end to provide an inner inclinedface 21 and formed with a slot leading from said wide open end to anarrow terminal seat 18 adjacent the inner end of the member, the slotbeing inclined to said seat to form a slideway 18 for the neck 12 andhaving at each side thereof guiding flanges 14 extending outwardly fromthe seat to the wide open end and whose inner inclined faces aredesigned to to propconsidered important that the head 13 be of a lengthconsiderably less than the distance between the sidewalls 14 vent anycontact whatever ofthe same, parthe neck travels in the slot or 1 inorder to preticularly at either of the low or high .points of theslideway. In this Way the neck 12 cooperating with the slideway centersthe door and looks it against vertical displacement, and the head inturn cooperating with the inclined face of the socket draws the doortightly against the doorpost or frame and holds it against lateralmovement.

In practice, it is considered preferable, that when the door is closed,the rear edge 10 thereof should project over the restricted end 19 ofthe socket sufficiently enough to Having 'thus described vmy inventionand D illustrated its use, what I claim as new and desire to secure byLetters Patent, is the following 1. In a door closure and lock device,the combination of a socket member comprising a base and a socketportion having its outer end provided with awide opening disposedsubstantially at right-angles with reference to said base, said socketportion formed lon-' gitudinally with an inclined slot leading from saidwide open end to providea relatively narrower terminal seat adjacent theinner end of the socket portion and having guide flanges extendingoutwardly from the seat to said open end at each side of the slot, and arelatively smaller sliding bolt member constructed and arranged to enterand pass through said open end for inward sliding travel in the slot toengage in said seat, said guide flanges inclined in an inward directiontoward said base and 006perating with the slot to guide the bolt memberin its inward travel to said seat.

2. In a door closure and lock device, the combination of a socket membercomprising an'attaching base and an inclined socket portion having itsouter end provided with a wide opening disposed substantially atrightangles ,with reference to said base, said socket portion havingits. web partially formed longitudinally with an angular slot -leadingfrom said wide open end to provide at its apex a relatively nafi'owerterminal seat in the inner end of the member and an inclined slidewayextending intermediately of said wide outer opening and the narrow seat,that portion of the web bounding the slot constituting a flanged guidemeans having an inner inclined face, and a sliding bolt member adaptedto enter and pass through said wide open end to said seat and comprisingan attaching base having a head adapted to slidably engage said innerinclined face and an intermediate neck portion adapted to slidablyengage said slideway in its travel to said seat. p

3. In a door 'closurefand lock device, the

, combination of an elongated socket member having an open outer end andcomprising spaced upper faces, respectively,

' guide flanges member is seated.

a base and a central body portion having a part of its web cut awaylongitudinally to provide a seat adjacent its inner end and and lowerguide flanges extending outwardly from the seat to said open outer end,the lower guide flange having an upwardly inclined face constituting aslideway to said seat and both of said flanges having inwardly inclinedinner guide faces disposed substantially at right angles to saidslideway, and a relatively smaller sliding bolt member constructed andarranged to enter and pass through said open outer end to said seat andcomprising angularly disposed locking portions adapted to slidablyengage said slideway and said inner guide substantially as described andfor the purpose set forth.

i. In a door closure and lock device, the combination with a sliding cardoor and car siding having a doorway opening therein, of alongitudinally disposed socket member secured to the car siding adjacentthe rear end of said opening and having an open outer end disposedsubstantially at rightangles to said siding, said member comprising anattaching base portion having a part of its web recessed longitudinallyand angularly to provide a restricted seat adjacent its inner end andspaced upper and lower guide flanges ex, tending in an outward directionfrom the seat to said outer openend, the lower guide flange having anupwardly inclined face constituting a slideway to said seat and saidhaving inwardly inclined inner guide faces disposed substantially atright angles to said slideway and at each side thereof, and a slidingbolt member 'secured to the rear portion of the door and adapted toenter and pass through said outer open end to engage the seat, saidmember comprising horizontally and vertically disposed locking portionsconstructed and arranged for slidably engaging said slideway and saidinner guide faces, respectively, the horizontal locking portion adaptedto maintain the door against movement in a vertical plane and thevertical locking portion adapted to maintain the door against outwardmovement in a horizontal plane when said door frame and its a slidingdoor for said opening, said door frame provided with a door postprojecting outwardly beyond the outer face of the frame to provide aclearance between the door and said frame; and a lock device 5.
